    Equipped for extreme environments

    in many applications within metal, mining and

    marine industries the demands on the equipment is

    exceptional. the machines are subject to exposure

    from mechanical loads, vibrations and shock in an

    environment of dust, liquids and high temperatures.

    they handle advanced machinery with utmost safety

    demands and economical value – failure may never

    be an option. such conditions require components

    of extraordinary durability, ready to meet extreme

    challenges in the field.

    robustness first

    the encoders in the 1000 series are designed based

    on one key requirement – offer the most robust

    mechanical solution possible. the space for ball

    bearings has been optimized, enabling a dual set of

    bearings with dimensions that are nothing less than

    extreme when it comes to encoders. the high encap-

    sulation level, iP67, protects the inner parts from

    dust and liquids, and as special option the housing

    can even be provided in stainless steel.

    modular, redundant and multifunctional

    the 1000 series is based on a modular concept

    with many options that can be combined into one

    multifunctional unit. one encoder unit may include

    dual incremental outputs for redundant speed feed-

    back together with an absolute position output with

    optional fieldbus technology. this gives a redun-

    dant and multifunctional encoder adapted for each

    specific application.

    outputs – electrical output interfaces

    incremental interfaces there are several variations of incremental interfaces with different supply voltages and signal levels. When choosing an interface, it is necessary to take into account factors in the application’s operating environment. the exact properties of the interface is affected by frequency, cable length and temperature.

    dual incremental outputs two separate encoder outputs can be combined into one and the same terminal box, equipped with two cable outlets. this solution provides added safety in the form of redundancy, the outputs are based on two separate scanning led:s and electronic circuits. the outputs are galvanically insulated from each other and may be connected to two separate systems for different function or for redundancy. the dual option is available for all incremental interfaces.

    ssi 25 bit ssi or synchronous serial interface is a digital point-to-point interface. it provides unidirectional communication at speeds up to 1 mHz by the use of only four wires. the ssi interface is available with 25 bit resolution, corresponding to 8192 unique positions singleturn and 4096 revolutions multiturn.

    Endat 25 bit the endat interface is a digital bidirectional interface. it is capable of transmitting position values from absolute encoders, as well as reading and updating informa- tion stored in the encoder. thanks to the serial transmission method only four signal lines are required. it is available with 25 bit resolution, corresponding to 8192 unique positions singleturn and 4096 revolutions multiturn.

    ProFiBus 25 bit ProfiBus is a powerful and versatile open fieldbus, defined by several international standards. leine & linde’s encoders follow the device profiles for dPV0 and dPV2. a ProfiBus system is set up with slave-to-slave communication, which means that slaves in a net can exchange information with each other without communication being initiated by the master. this type of communication is very efficient and fast and reduces the response time on the bus by up to 90%. ProfiBus encoder func- tionality includes position read out, changed direction of counting, diagnostic data, scaling function, preset value function, as well as velocity read-out. the ProfiBus interface is available with 25 bit resolution, corresponding to 8192 unique positions singleturn and 4096 revolutions multiturn.

    Parallel 13 bit Parallel output provides an absolute position available simultaneously on the output. the signal is transferred over one separate cable wire per bit, which gives the advantage that all the data is available in real time, all the time. the parallel output is available with up to 13 bit singleturn resolution.

    CrG overspeed the crG overspeed features a pre-programmed frequency value for overspeed indication. if the limit speed is reached a mechanical relay will change state to indicate overspeed to the system. a typical solution is to use a 1000 series encoder with two separate terminal boxes – one for an incremental signal output connected to the motor drive system, and the other for the crG overspeed function with relay outputs for alarm. in safety critical applications it is also important to know that the control system itself is reliable. therefore the crG overspeed features advanced logic to monitor that the encoder’s basic function is reliable at all moments. functionality includes redundant overspeed outputs as well as monitoring of signal detection, state transition and encoder diagnostics. this combined overspeed and function monitoring system makes the crG overspeed a unique product for safety applications where a reliable speed is required.

    encoder output signals are available in a variety of different interfaces. consult page 4-5 for

    possible combinations and put together your own encoder with up to four separate outputs.
